`GAS-sunrise.

SPECIFICATION forming part of Letters Patent No. 291,480, dated January1, 1884. Applicatbn filed June 12, 1883. (No model.)

. T all whom t may concern,.-

i State of New Jersey, have invented a certain new and usefulImprovement in Gas-Burners,

of which the following is a specification.

This improvement consists in a novel m'ethod of suspending a gasburncr,and it includes a means whereby the heating of the gas before itsarrival at the burner tip or tips will be ef fected.

In the accompanying drawings, Figure lis Y p a central vertical sectionof a gas-burner and appurtenances embodying my improvement. Fig. 2 is ahorizontal section of the same, and Fig. 3 is an inverted plan or bottomView thereof.

Similar letters of reference designate corresponding parts in all thegures.

A designates an `annular burner-tip having apertures for the escape ofjets of gas at its apex, and supported by a number of hollow arms, a,which extend to it from a central body-piece, b, and conduct gas to itfrom the said body-piece. In the body-piece b of the burner-tip is acentral cavity, into which the gas is conducted. The gas which is to beused in the burner is supplied from any suitable source through a pipe,B. .This pipe B is screwed into-a disk, C, and communicates with asimilar pipe, D, also screwed into said disk, but extending downwardlytherefrom. The pipe D is open at the lower end and extends nearly to asecond disk, E. A pipe, F, considerably larger than the pipe D, isscrewed into the diskFi in such position as to be conp centric with thepipe D. A shell, G, ext-ends between the disks C E. As shown, it entersa groove in the under side of the disk C and screws on the exterior ofthe disk-E.

H designates a pipe extending downwardly from the disk E, and, as hereshown, it is secured thereto by being screwed onto adownwardly-extending flange. Passages. or ducts c extend through thedisk E and establish communication between the space outside the p pipeF, within the shell G and the pipe H. The lower end of this pipe H isconnected with the central cavity in the body-piece of the burner-tip' Aby means of a taper pipe, I.

The pipe I is shown as being screwed into the piece of the burner-tip.

Arms J, adjustably secured to certain of the arms a of the burner-tip,serve to support a chimney, K, which is shown as cylindrical in `pipe Hand upon the exterior of the body` shape, and may be made of glass. Thearms J are longitudinally slotted, and are secured to the arms a byscrews passing through their slotsand entering the arms a.. This chimneyK extends above the lower portion of the shell G.

L designates a number of pipes extending from the disk E to the disk C.These pipes are shown as being screwed into the disk E, but they arepreferably expanded into the disk C. They secure the disks together.These pipes are arranged in a circular row or series close to theinterior of the shell G. Gas, entering the pipe B, passes downwardly toand through the pipe D, thence into the pipe F, and thence upwardlythrough this pipe F into the space inclosed by the disks C E and theshell G. From the shell G the gas passes through the apertures cinto thepipe H, thence into the pipe I, thence into the body-piece of theburner, and thence through the arms a, into the burner-tip. The airnecessary to support combustion enters between the arms a to the spaceencircled by the burner-tip., and betweenthe arms J to the space whichis between the burner-tip and the chimney K. The products of combustionpass up around the pipe H and heat the gas therein. Ascending above thepipe H they enter the pipes L, and thence escape into the atmosphere. Inpassing through the pipes L the escaping products of combustion heat thegas which is in the shell G.

Around the pipe H is a piece of incandescing material-such as porcelainor abestus. It is shown as externally of an inverted conical form, sothat it will form a deiector for throwing air against the interior ofthe flame.

A circular series of burner-tips may be used in lieu of a single annularburner-tip.

I have obtained Letters Patent for improve- ,ments in gas-burners, No.278,568, dated May IOO burners, for which I have iiled applications forLetters Patent on November 4, 1882, Serial No. 77,087; June 6, 1883,Serial' No. 97,245; July 2, 1883, Serial No. 99,750, and July 11, 1883,Serial No. 100,490. In my .present application I do not desire to claimanything that is covered by my Letters Patent and applications abovereferred to.

By the arrangement of the pipes D Fand the shell G, I cause the gas topass a greater distance while subjected to heat from the escapingproducts of combustion than in my other improvements, because the gashas to descend to the bottom of the pipe D, then aseend to the top ofpipe F, and finally descend tothe bottom of the shell G, thereby passingthree times a distance equal nearly to the ylength of the shell G beforeescaping` into the pipe H. By making th'e pipe H nearly as large as theannular burner-tip or series of burner-tips and leaving it uninterruptedby any pipe passing through it I provide a chamber of large capacitythrough which the gas passes sluggishly, and in which the gas is iinallyheated to a high degree before passing to the burner tip or tips. Itwill therefore be l seen that I provide a long passage consisting of theintercommunicating pipes D F and the shell G, in which the initalheating of the gas will be performed, and alarge c h amber through whichthe gas will pass so slowly that itsiinal heating will be eectivelyperformed. The pipes H and I serve the additional purpose of a supportfor the, burner tip or tips.

What I claim as my invention, and desire to secure by LettersPatent, is-

1. rIhe combination, with the upwardly-ex;

tending annular burner-tip 'A or a circular series of burner-tips, ofthe downwardly-extending gas-supply pipe D, and the pipe II I,communicating with the pipe D and extending'downward to a centralbody-piece, whence gas is supplied to the burner tip or tips, and mademuch larger than the pipe D, so as to form a chamber wherein the gaswill be heated by the flame and ascending products of combustion,substantially as specified.

2. In a gas-burner, the combination of a gas-supply pipe by which theburner is to be suspended, and which is open at the lower end, a secondpipe of larger size surrounding the gas-supply pipe, closed at the lowerend and open at the upper end, a shell surrounding said second pipe andcommunicating with the open upper end thereof, a third pipe arrangedbelow and communicating with said shell, and an annular burner-tip, or acircular series of burner-tips supported by the lastmentioned pipe, andto be supplied with ga therefrom, substantially as specified. l

3. The combination, with an annular burner-tip, or a` circular series ofburner-tips, of the pipe B, the shell G, connected to the disks C E, apipe establishing communication between the space inclosed by the saidshell G and a central body-piece, whence gas is supplied to the burnertip or tips, a chimney, and the pipes L, arranged within the shell G,substantially as specied.
